Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz mechanism movements, both manufactured by Seiko, are frequently seen in their watches, yet subtle distinctions exist. The PC21J is generally considered the earlier model, featuring a typical three-hand display – hours, minutes, and seconds. Its reliability is generally within ±15 seconds per duration. In contrast, the PC21S represents a subsequent iteration, most notably known for its ability to show date information. This capability adds intricacy to the movement and can slightly impact its overall consumption. While both movements share a akin architecture and operate on the same fundamental principles, the PC21S's date addition results in a slightly increased parts number and potentially a marginally smaller battery time.
